The owners of Blue Mash golf course in Montgomery County are seeking an exemption from a county tax they feel makes it harder for them to compete with public golf courses operated by the county.

Montgomery County Council Member Mike Knapp will introduce a bill today that would exempt the privately owned Blue Mash course in Laytonsville and Trotters Glen in Olney from the 7 percent admissions and amusement tax the courses are charged on their gross receipts.
